She texts her friend to come over, you'll see that there's nothing to worry about. Ok yes, he's hot, they met at the gym, but they're JUST friends. She shows you how she blows him, in a friend way. You watch as he cums in her mouth, she swallows and you tell her that was 100% cheating.
So she tells you she will try even harder to prove her innocence. She'll fuck him with a condom, there's no way you think that's cheating!
But after watching your GF being fucked doggystyle you tell her you don't like what she's doing, it certainly is cheating. Now she's mad. If you think she's cheating they may as well fuck without the condom.
You made her do this. You made her cheat. This is all your fault. You should have just agreed with her in the first place! Now she has a pussy full of her friends cum. If she's pregnant, it's all your fault.
